APPARATUS FOR CONVEYING GRANULATED MATERIALS.

SPECIFICATION forming part of Letters Patent No. 675,382, dated June 4, 1901. Application filedMaroh 15,1 01. Serialllo. 51,376. (No model-i To all whom it may concern.-

Be it known that I, KARL FRoHNHAUsER, engineer, a subject of the Emperor of Gerscription of the invention, such as will en-' able others skilled in the art to which it appertains to make and use the same.

The present invention relates to an improved apparatus for conveying granulated materials, such as coal, sand, and thelike.

The invention consists in the combination of known mechanical means employed for this purposesuch as, for instance, endless chains and such like-With a stream of water moving in the direction in which the material is being transported.

Of the accompanying drawings, Figure l is a sectional side elevation of my improved apparatus; Fig. 2, a plan view of the arrangement shown in Fig. 1; Fig. 3, a plan view of a'niodification. Fig. 4 is alongitudinal sectional view, on an enlarged scale, of the conveyer-trough and parts therein. Fig. 5 is a transverse sectional view of' the parts shown in Fig. 4.

The same letters of reference designate the same parts in all the figures.

b is a long trough or gutter open at the top and arranged to connect the two points between which the conveyance of the material is to take place.

e is a water-pipe connecting the ends of the trough b and provided with a cock d.

f is an endless chain provided with paddlesand carried around a suitable number of pulleys z 'i, by the rotation of which it can be kept in motion.

a is a hopper by which the granulated material can be fed into the apparatus, and c is a second hopper, by which the material is discharged after passing along the trough b.

In the modification shown in Fig. 3 the number of troughs b is multiplied and they are all connected at the discharge end by branches h, which lead the water into a com- The operation of the herein-described apparatus is as follows: The trough b is kept full of water by any convenient means of supply. The material-for instance, coalis continuously or periodically fed into the hopper a. Here the chain f, being constantly kept in motion,.seizes the material and with the aid of the water easily distributes it and spreads itout along the trough band carries it onward toward the discharge -hopper o. The effect of the water is to considerably reduce the weight of the material that is being conveyed and at the same time as the water, as well as the material, is kept in constant motion by the chain it washes along the latter, and thereby aids the .action of the paddles in conveying the material.

In the modification of my apparatus shown in Fig. 3 no chain is supposed to be provided in the branches 71, because the amount of wa-' ter passing through these parts'in the unit of time will be greaterv than that passing along the branches b, and therefore the wash of the water alone will in these parts be sufficient to convey the material.

I am aware that the method of washing granulated materials along a trough or canal by means of a stream of water is not new, and I am also aware that mechanical meanssuch as endless chains, endless bands, and the.like-are also usually employed for conveying materials of this kind from one place to another; but, as I have particularly described in the foregoing specification,

What I claim as my invention is 1. In a conveyer for granulated material, the combination of a trough or conduit on the floor of which the material issupported while being transported, a body of liquid in said 3. In a conveyer for granulated material, the combination of a trough or conduit on the floor of which the material is supported while being transported, a body of liquid within said trough and into which the material to be moved is delivered, an endless power-transmitter extending for a portion of its length through said liquid and adapted to move material therein longitudinally of the conduit and cause a movement of the liquid in the same direction, for the purpose set forth.

4. In a conveyer for granulated material, the combination of a trough or conduit on the floor of which the material is supported while being transported, a mechanical conveyer operating in said conduit to move said granulated material longitudinally thereof, and means for continuously supplying Water to said trough or conduit, for the purpose set forth.

5. In a conveyer for granulated material, the combination of a trough or conduit, a body of water in said conduit, a mechanical conveyer operating in said conduit to move the granulated material and water therein longitudinally thereof, and means for repeatedly returning the water to the trough or conduit.

6. A11 apparatus for conveying granulated materials consisting of a trough, an endless chain provided with suitable paddles, means for keeping said chain in motion along the bottom of said trough, a sulficient supply of Water in said trough and moving under the impulse of the paddles in the direction of the motion of the material, and a conduit connecting the ends of the trough for conducting water in a direction opposite to that in which the paddles move through the trough,

substantially as and for the purposes set forth. In witness whereof I have hereunto set my hand in presence of two witnesses.
